Abstract (en)

[origin: WO2010012529A1] A description is provided of a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials, said roller mill (1) comprises a mill housing (2), a substantially horizontal grinding table (3) and a number of rollers (4) each rotating about a roller shaft (5) which is connected to a rotatably vertical shaft (6) centrally positioned relative to the grinding table (3) where the rollers (4) are configured for interactive operation with the grinding table (3). The roller mill is characterized in that the grinding table (3) is stationary and in that it (1) comprises means (8) for introducing gases into the mill housing (2) and means (7) for continuously diverting ground material suspended in gases out of the mill housing (2). As a consequence hereof, the process for a roller mill with a stationary grinding table will be continuous and the diameter of the grinding table will not be subject to limitations.
